About the kinetic energy of spacecraft and simulation

Hi,
I’m new to SPIS but I would like to use it. However, I have many difficulties.
How could I calculate the kinetic energy of the spcecraft? I can only get the electric field but do not know the magnetic field or the velocity of the satellite.I would like to know the current capabilities of the SPIS software (and whether it would be easy to extend the code) about this.
And when I finished the simulation, many of the graphs were just blank. What’s wrong with my simulation?
Please, I need help!Best regards

The spacecraft velocity and magnetic field is set in the global parameters. Read the documentation and come back
